1 |
Problem |
A billiards table has a horizontal radius of measurement 8cm and a vertical radius of 5 cm. Calculate the area of the ellipse. (π = 3.14) |
|
2 |
Step |
Given that the horizontal radius (a) is the vertical radius (b) is |
8 cm 5 cm |
3 |
Formula: |
To calculate the area of an ellipse, you can use this simple formula |
\$"Area" = π times "horizontal radius" times "vertical radius"\$ |
4 |
Step |
Substitute the values into the formula |
Area = \$3.14 times 8 times 5\$ Area = \$125.66(cm)^2\$ |
5 |
Step |
So, the area of the ellipse is \$125.66(cm)^2\$ |
|

Sumup |
Can you summarize what you’ve understood in the above steps? |
|
7 |
Choice.A |
This option is incorrect, significantly exceeding the calculated area size |
\$540.5(cm)^2\$ |
8 |
Choice.B |
This is the correct option. It matches the calculated area of the \$125.66(cm)^2\$ when rounded to two decimal places |
\$125.66(cm)^2\$ |
9 |
Choice.C |
This option is incorrect, significantly exceeding the calculated area size |
\$504.5(cm)^2\$ |
10 |
Choice.D |
This option is incorrect, significantly exceeding the calculated area size |
\$545.5(cm)^2\$ |
